Fix it First: Utilizing the Seismic Property Analyzer and MMLS to Develop Guidelines for the Use of Polymer Modified Thin Lift HMA vs. Surface Treatments

Currently many of the New England states are adopting the “Fix it First” approach when faced with decisions to construct new pavement systems versus rehabilitating the existing pavement. This approach has been further backed by many of the state legislators who have allocated funds earmarked for “Fix it First” projects... read more

Laboratory and Field Evaluation of Warm Mix Asphalt Technology to Determine its Applicability for Massachusetts

Some of the most recent innovations in Hot Mix Asphalt (HMA) technology have originated from Europe and migrated to the United States. These include Stone Matrix Asphalt (SMA) and Permeable Friction Courses (PFC). The latest import from Europe is Warm Mix Asphalt (WMA) technology... read more

Validation and Correlation of Pavement Profiling Devices for Quality Control/Quality Assurance

American Society for Testing Materials (ASTM) defines pavement roughness as, “The deviations of a surface from a true planar surface with characteristic dimensions that affect vehicle dynamics, ride quality, dynamic loads, and quality.” Most State Highway Agencies have used pavement roughness data as a measure of construction quality control and as an indicator of the need for rehabilitation... read more

NETC 02-1 Relating Hot Mix Asphalt Pavement Density to Performance

Density is one of the most important properties of Hot Mix Asphalt (HMA). Most of the currently used mix designs rely primarily on achieving optimum densities, and most Quality Assurance (QA) specifications used by state department of transportation use density as a critical parameter... read more

NETC 04-4 Determining the Effective PG Grade of Binder in RAP Mixes

The use of reclaimed asphalt pavement (RAP) material is increasing as local, state and federal transportation agencies make more efficient use of their resources. RAP material is generated when old, damaged pavement materials are milled and crushed for addition as a component to new mixtures placed in the pavement structure... read more
